For the larger hook, I really do mean a large bait. I have seen many anglers put on a single worm with a strip of squid on the end, but they have tended to catch smaller fish. I do this to the beaded side, but I put on three large ragworm or lugworm and at least a six inch strip of launce (greater sandeel) on the other.
The results can be terrific! I had one drop where I had a 2 lbs 10 ozs plaice on the beaded side and a 3 lbs 12 ozs fish on the other. With 6 lbs main line and a baitcaster I then had an excellent fight to get them on board.
The use of launce is well worth a mention. Twenty years ago, if people were going to fish over marks like the Skerries, they would stop on the way out and jig traces of small, silvery, flies hard on the bottom to catch enough launce to use as bait, bumping the weight on the bottom to flush them from the sand and get their attention. Nowadays that does not often happen. People come on board with frozen squid from the fishmongers and steam straight to their intended mark, aiming to get the maximum available fishing time.
Now you can appreciate their logic, but fresh launce would enable them to target much larger fish than they could with frozen squid. Since I switched to launce I have found that, on average, I tend to catch a specimen plaice at the rate of at least one every two or three trips. It does make a difference.
Nowadays, instead of using standard leger tackle for the first part of the rig, I often use a boom instead. This tends to make tangles a thing of the past.
